From the original (inedited) prize essay in French, crowned by the Academy in 1886/87. These two articles comprise the introduction and pt. 1 ("Philosophie") only. A 2d part ("Mathematik") appeared in Zeitschrift der Deutschen morgenl. ges., bd. 50, 1896; and a 3d part (Die griechischen aerzte in arabischen uebersetzungen) in Virchow's archiv, bd. 124, 1891. Twenty-four sets of separates of these articles combined with a reprint of an earlier essay, "Euklid bei den Arabern" (from Zs. f. math. u. physik, XXXI, 3) were made up and placed on sale in 1897
